My invention has particular relation to operating means for operatingthe usual. opposite shutters of skylights althoug'hnot l1mited to thisuse alone. I

The main object .of the invention resides the provision of slmple andeffective means whereby. either of two reciprocable members may bepositioned to either end of its move ment while the other is ateitherendof-its movement through the medium of a single f operating member. Asapplied to theopera tion of opposite shutters of askylight both shuttersmay. be .fullyopened or closed or either maybe fully opened or closedwthout necessitating-the otherbeing in any particu z ,lar posit-ionsuehas closed position, thus providing a universal controlof the oppositeshutters through the medium .of a single op erating member, whereby--where distant op eration is necessary or convenient as 1s usual trainof distant control mechanism-is neces; sary. u t if .With th s ob ect1n,v1ew my lnvent on con- Pa b other objects hereinafter-v appearing areef fected. allas fully describedwith reference, to the accompanyingdrawings and more particularly pointed out in the. claims. in thesaiddrawings my lllVGntlOIlfOI operating theoppositeshut ters of theskylight.

A.pair of links 21 arepivotally secured at their opposite ends to thelower endsof respective arms. 18 and toirespective links 5 whereby resciprocable movement of the'arms williopen and close respective sets of,shutters4, ;and v .the brackets 17 are provided with oppositestops22-which limit the opposite, i. e,- shut- 1 ter. opening andclosing, movements of respe'c tiv'e arms 18. ,The arms 18'ar'econnected'to :IGSPGOUVG ad acent crank pins 16;by. longhthereof, a cylindricalblock 27 disposed within the portion 24for longitudinal slidingmovement, and two coiled compression springs 28 disposed within theportion 24 at respective ends of the block 27 and respectively abuttingthe head 25 and plug 26 and abutting the block whereby to resilientlymaintain the block in its normalposition at an intermediate point in itsmovement within the portion 24. See Fig. 4. The block 27 is pivotallysecured'to the res )ective arm 18 by a headed stud 29 passing t roughdim metrically-opposite longitudinally extending slots 31 in the tubularportion 24 and a diametrical bore in the block 27 for pivotal movementtherein and screwthreaded into the respective arm 18.

The arms 18 are moved between the stops 22 by angular movement of therespective gears 14 by means of the crank pins 16 and connecting rods 23whereby the respective shutters are opened and closed. The throws of thecrank pins 16- are excessive so that the arms 18 engage "the stops 22 atboth ends of I their movements before the crank "pins reach thelinesintercepting the axes ofrespective gears and the axes of respectivestuds 29. In this case the arms 18 engage respective stops when there isstill 15 of angular dis tance between the-res tive crank insand therespective lines. he springs 2 permitting theblock'27 to move in thetubular portion 27 of the connecting rods 23 provide for theadditionalmovement of the crank ins so that in the cycle of each gearlithe strokin of the respective arm 18 is alternated wit periods duringwhich the arm 18 is held 7 against respective stops 22, during'one t erriod the arm 18 being held in closed sh position and during the otherperiod it being held in open shutter position. As shown these periodseach embrace 90 in the angular movement of respective gears 14.

As hereinbefore stated the crank pins 16 are sequentially timed at 90 sothat the stroking riods of each arm occur during the periods when theother arm is held against one of the respective stops whereby eitherarmmay be positioned to either end of its movement while the other armis positioned at either end of its movement. The result is that eitherof the opposite sets of shutters maybe positioned in open or closedposition while the other is positioned in either-open i new and desireto secure by Letters Patentthe following. I I V silientconnections cooor closed position thus providing universal adjustment thereof. rs 4:are as is obvious operated by the shaft 8 through the small gear 13whereby the universal control of the shutters is provided through asingle train of mechanism. It will be further observed that themechanism permits of a plurality of shutter operating mechanisms beingdisposed at points along the operating shaft 8 and operated in unisontherefrom.
